Relo v2.0 Beta 3 Released

Beta 3 of Relo v2.0 has been released. This will be the last beta version preceding version 2.0. The 2.0 release should happen in about a week, with very few (if any) changes.

Some changes:

Overhaul of the project manager; it now stores file info and source/header file relationships more efficiently, and is much faster loading projects, and checking and compiling source files and building projects.

Checking for file changes - user is notified if a file changes outside of Relo and is prompted to reload it
